/* "Rotating trees" (Armin Rigo)
*
* Google "splay trees" for the general idea.
*
* It's a dict-like data structure that works best when accesses are not
* random, but follow a strong pattern. The one implemented here is for
* access patterns where the same small set of keys is looked up over
* and over again, and this set of keys evolves slowly over time.
